The Grand Prix series is the biggest and best sitting volleyball competition in England. 

Split into two tiers, it sees teams from each group play in six round-robin format events throughout the season. League standings decide who plays in the Final 4 before a climactic final to crown the champion.

Throughout the 2022/23 season there were fierce battles for the top 4 spots in the league with just two wins separating the top 3. Sitting Bucks successfully retained their title by beating Help 4 Heroes in the final.
